The main reason was that mandarin film producers wanted to release their films in first - run cinema circuits showing western films but such cinemas were few and far between and generally had limited dates scheduled for screening mandarin films . mandarin producers were reluctant to show their films in second - run cinemas or cantonese film circuits 原因是片商选择在放映首轮西片的戏院上映,但这些戏院给予国语片上映的档期无多,他们又不愿降格在二轮西片和粤语片院线放映那些影片。
